Heating Drum.

Patent-ed Dep. 22, 1868 j Wsw/M N4 PETERS. PHOTO-LITNCG WASHINGTON D Cltimid 5ta-tw @anni The Schedule referred to in these Letters Patent andmaking part of the same.

To all whom it 'ma/y concern:

Be it known that I, JOHN AnAMs, of Findlay, in the county of Hancock,and State of Ohio, h-ave invented a new and useful Improvement inStove-Drums; and

I do hereby declare that the following is a full, clear,

and exact description thereof', reference being had to the accompanyingdrawings, in which- Figure 1 is a central verticall section through theline :v :c of fig. 2, and

Figure 2 is a horizontal'section through the line y g; of iig; l.

The nature of my invention consists in the. peculiar arrangement ofcones or chambers and fines, ashereinafter described. Y

To enable others skilledsin .the art to make anduse my invention, I willproceed to describe its construction and operation.

In the drawing- A A represents the pipe which leads from the heater.

To the upper end oi' the pipe A is attached a cone or chamber, B..

Inside. of this cone is another, C, at the bottom of which is a damper,D.

In the top of the cone or chamber C is an aperture, around which isplaced the pipe`E for the direct draught, and the escape of gas andheat.

Around the pipe E,Yand above the cone or chamber B, is another cone orchamber, F.

The cones or chambers B and F are connected together by a series of ues,Gr.

. These ilues are double,.being divided at or near their.

centres by a" partition, H.

These flues are arranged so that the partition I-I comes directly overthe outer edge of the cone or chamber G.

Its operation is as follows:

The heat or steam passes up vthrough the pipe A; thencawhenl the damperD is closed, up outside the cone C, through the outer passage of thelues Gr, into the cone or chamber F; thence, through the inner passageof the iiues Gr, into the cone C, and from that escapes through the pipeE.- The direction of the heat is indicated by the arrows in g. 1.

By opening-the damper D, the heat will pass directly up through the`cone O, andv out through the pipe E. y y

Having thus fully described my invention,

What: I claim, and desire to secure by Letters Patent, is Y p 1. Thedouble fines G, when constructed and arranged substantially as shown anddescribed.

2. The combination ofthe cones or chambers B G and the damper D,substantially as shown and described.

3. The combination of the cones or chambers B F Vfand the lues G,substantially as shown and described.
